INTRODUCTION
Hatco Glo-Ray
®
Strip Heaters ensure maximum
food holding and minimize the risk of food-borne
illness. Optimum safety and quality is the result of
food held at the proper serving temperatures, using
Glo-Ray’s pre-focused heat patterns. The pre-
focused heat pattern prevents foods from being
over-cooked in the middle and cooling off around
the edges by concentrating higher temperatures to
the outer edges of holding surfaces where heat loss
is the greatest. Utilizing specially designed
reflectors to direct the heat from the element, Glo-
Ray Strip Heaters safely maintain peak serving
temperatures longer, without cooking the food
beyond the point of excellence.
The Glo-Ray Strip Heaters are available with or
without shatter-resistant incandescent lights to
illuminate the warming area. These bulbs have a
special coating that guards against injury and food
contamination in the event of breakage.
This manual provides the installation, safety and
operating instructions for the Strip Heaters. We
recommend all installation, operating and safety
instructions appearing in this manual be read prior to
installation or operation of your Hatco Strip Heaters.
Safety instructions that appear in this manual after a
warning symbol and the words WARNING or
CAUTION printed in bold face are very important.
WARNING means there is the possibility of
serious personal injury or death to yourself or
others. CAUTION means there is the possibility
of minor or moderate injury. NOTICE without the
symbol signifies the possibility of equipment or
property damage only.
Hatco Strip Heaters are a product of extensive
research and field testing. The materials used were
selected for maximum durability, attractive
appearance and optimum performance. Every unit
is thoroughly inspected and tested prior to shipment.

IMPORTANT SAFETY INFORMATION
WARNINGS
Only light bulbs which meet or exceed NSF
standards, specifically designed for food
holding areas may be used. Breakage of light
bulbs not specially coated could result in
personal injury and/or food contamination.
Units equipped with a cord and plug supplied
by Hatco must be plugged into a properly
grounded electrical outlet of the correct
voltage, size and plug configuration. If the
plug and receptacle do not match, contact a
qualified electrician to determine the proper
voltage and size and install the proper
electrical outlet.
For safe and proper operation, the unit must
be located the correct distance from
combustible walls and materials. If safe
distances are not maintained, discoloration
or combustion could occur. Refer to specific
installation and mounting information in this
manual for proper clearances.
To prevent any injury or damage to the unit
do not store or use gasoline or other
flammable vapors or liquids in the vicinity of
this or any other appliance.
The unit is not waterproof. DO NOT submerge
in water. Do not operate if it has been
submerged in water.
To prevent combustion or damage to
materials do not install standard wattage strip
heater (GR, GRA, GRN, GRAL Series) less
than 10" (254 mm) above a non-metallic
surface. Do not install high wattage strip
heater (GRH, GRAH, GRNH, GRAHL Series)
less than 13-1/2" (343 mm) above a non-
metallic surface. Do not install dual strip
heaters (GRA-XXD, GRAH-XXD, GRAL-XXD &
GRAHL-XXD Series) above non-metallic
surface. Install all non-dual strip heaters so
there is a minimum distance of 3" (76 mm)
from a non-metallic wall or adjacent surface.
To avoid any injury or damage to the unit
when using chains for installation, the chains
must have sufficient strength and be
securely fastened, or the unit could become
loose or fall. Do not place anything on top of
warmers supported by chains.
To avoid any injury or damage all electrical
connections must be in accordance with
local electrical codes and any other
applicable codes. Connections should be
made by a qualified, licensed electrician.
To avoid any injury or damage to the strip
heater turn the power OFF at the disconnect
switch/circuit breaker and allow to cool
before performing any maintenance.

IMPORTANT SAFETY INFORMATION
MODEL DESIGNATION
CAUTIONS
Standard and approved manufacturing oils
will smoke up to 30 minutes during initial
start-up. This is a temporary condition. To
assure safe operation, operate unit without
food product until smoke dissipates.
Some exterior surfaces on the unit will get
hot. Use caution when touching these areas
to avoid injury.
To prevent unit failure do not add a
decorative soffit to hide a pass-through
mounted Glo-Ray Strip Heater.
Strip Heaters with incandescent lights that
require a circuit breaker larger than 20 amps
must have a separate circuit breaker for the
incandescent lights that is 20 amps or less.
To assure safe and proper operation refer to
Installation Clearance Requirements listed in
this manual.
Installation of two or more single units with
less than 3" (76 mm) between housings may
result in premature failure of component
parts.
Unit is not moisture proof. Spacing of at least
16" (406 mm) is required for all units mounted
over a steam table.
NOTICE
Use only non-abrasive cleaners. Abrasive
cleaners could scratch the finish of your
unit, marring its appearance and making it
susceptible to dirt accumulation.
To prevent premature failure to components
the Remote Control Box (RMB) must be
installed outside the strip heater heat zone.
Heat damage to countertop material such as
Corian
®
and similar products (other than
stainless steel) is not covered under the
Hatco warranty. Contact the manufacturer of
the base material for temperature limits and
application information before installing the
unit.

Chain Mounting
WARNING
To avoid any injury or damage to the unit when
using chains for installation, the chains must
have sufficient strength and be securely
fastened, or the unit could become loose or fall.
Do not place anything on top of warmers
supported by chains.
Chain supplied by Hatco is constructed of sufficient
strength to securely hold the weight of the unit only
when properly mounted.
1. Securely fasten the chain to the surface above
the desired area. Be sure chain is located so the
unit will be suspended at a safe and proper
distance from walls, counter and food.
2. Loosen but do not remove the screws securing
the mounting tabs on each end of the unit.
Extend the tabs, then tighten the screws
securely. (See Figure 20.)
3. Attach a short piece of connecting chain to each
pair of mounting tabs. (See Figure 20.)
4. Attach overhead chain to the connecting chain
between the two mounting tabs. Repeat for other
end of unit. (See Figure 20.)
NOTE: Additional chain will be needed for dual
Glo-Ray units.
Chain Mounting with “S” Hook
Units supplied from Hatco with power cord attached
come with the connecting chain and “S” hook
already attached to the mounting tabs.
1. Securely fasten the chain to the surface above
the desired area. Be sure chain is located so the
unit will be suspended at a safe and proper
distance from walls, counter and food.
2. Attach both “S” hooks to the overhead chains
and ensure the unit is level. (See Figure 20.)
